An AI co-founder that helps you think through ideas before you sink time into them. Chat with it, get a viability score, generate a PRD, and walk away knowing whether to build or move on.

Most ideas die not because they're bad, but because they're underthought. You get excited, you start building, and three weeks in you realize the market's wrong or the problem isn't real. The cheapest fix is thinking harder before you write code — but most people don't have a co-founder to bounce ideas off of.
Idea Foundry is that co-founder. It adapts its mode — supportive when you need encouragement, challenger when you need honesty. It scores viability, maps competition, and turns the conversation into a structured PRD you can actually hand to a developer.
- AI Co-Founder chat — supportive or challenger mode, adapts to your stage
- Viability scoring — market potential, competition, problem-solution fit
- PRD generation — turns conversations into structured product requirements
- Synergy analysis — finds cross-promotion opportunities across your projects
- Voice interaction — speak your ideas, hear the feedback (client-side TTS/STT)
- GitHub export — push generated PRDs directly to a repo
- React + Vite + TailwindCSS + shadcn/ui — frontend
- Node.js + Express — serverless-ready API (Vercel)
- PostgreSQL via Drizzle ORM — Neon Postgres in production
- Google Gemini + Anthropic Claude — provider routing with automatic failover; if Gemini's down, Claude picks up
- Supabase Auth — magic link authentication
The AI routing is the interesting piece — it's not just "call the API." It routes across providers with per-request failover, so a Gemini outage doesn't take the app down. Each provider has its own adapter, and the service layer picks based on availability and cost.
